[Debichem-devel] Bug#808312: chemps2: fails to upgrade from 'testing' - trying to overwrite /usr/share/man/man1/chemps2.1.gz

[Andreas Beckmann]

Package: chemps2
Version: 1.6-2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'testing'.
It installed fine in 'testing', then the upgrade to 'sid' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

>From the attached log (scroll to the bottom...):
